Sinojackia xylocarpa is an endangered plant species endemic to China. Here, we assembled its complete chloroplast genome from Illumina sequencing reads. The circular genome is 158,725 bp long, and contains a pair of inverted repeat regions of 26,090 bp each, a large single-copy region of 87,994 bp and a small single-copy region of 18,551 bp. It encodes 137 genes, including 91 protein-coding genes (82 PCG species), 38 tRNA genes (31 tRNA species) and eight rRNA genes (four rRNA species). Fifteen gene species harbor a single intron, while another two gene species have a couple of introns. The base composition is asymmetric (31.1% A, 19.0% C, 18.2% G & 31.7% T) with an overall A+T content of 62.8%. Phylogenetic analysis corroborated the traditional family-level taxonomy of the order Ericales, and suggested that S. xylocarpa is closely related to Alniphyllum eberhardtii and Bruinsmia polysperma within the family Styracaceae.
